MOPSTICK HEAD;

Application mea June 1e, 1923. serial No. 645,745.

To all whom1 it may con-cern;

Be it known that I, BELDEN L. CONCHAR, a citizen of the United States, residing at Maplewood, in the county of Essex` and State of New Jersey,l have invented certain new and .useful Improvements in Mopstick Heads, of which the following is a full, clear, and exact description.

This invention relates to mop stick heads having` a groove along the outer endL edge in which mop cords or cloths may be i clamped by a wireor other clamping element which passes ,along the groove and is adjustably secured to the handle. Devices of this type commonly employ a cylindrical 4coil spring which is secured at one end to the mop stick adjacent the grooves or clamping head, and which is varticulately connected to the means for operating the wire or clam'pingelement into and out of clamp? `ing engagement withpthe head. The coil spring is commonly anchored against movement endwise of the stickI by a staple which `also serves to anchor the cross head'to the end of the mop stick. vIt is necessary to prevent the vcoil spring from rotating about the mop stick as an axis, because such a rotation might disengage the spring from j beneath the staple and allow it to slide end- 'wisedown themop stick. The mop stick is commonly cylindrical and lits in a cylin- 'A with the tight fit between the stick and.

drical socket'in the vcross head, the staple which anchors the head to the stick serving,

socket, to'prevent rotation of the head Vrelatively to the stick. The moisture to which the mop is continuously subject soon rots p ,the wood around the staple suliiciently to cause'the head to become loose and hinder the manipulation ofthe mop in use.

An object ofthe invention is to provide anV improved mop of this type in which relative rotation between the clamping head and mop stick will be effectively prevented; in which the spring will be effectively held against turning upon the mop stick with-v outreliance `upon the anchoring staple; withy which the assembly of the-parts of the mop is facilitated;l andwhich is 'relatively strong,- durable and inexpensive. Various other objects and advantages will be apparent from the following description of anembodiment of the invention, and the novel -features will be particularly pointed out hereinafter in claims.

In the accompanying drawing:

Figure 1 is an elevation of a mopl constructed in accordance with the invention;

Fig. 2 is an end view of the same;

Fig. 3 is a section through the same taken substantially along the line 3-3 of Fig. l.

In the illustrated embodiment yof the invention two sheet metal stampings l and 2 are secured together, face to face, in any suitable manner such as by interlocking cut out tongues 3. The stampings at their outer ends are bent away from one another so as to form a shoulder and then substantially at. right angles thereto, as at4, which will be parallel to their original planes,.to form between the last mentioned angular vportions a U-shaped channel or groove in which the mop cloths 5 may be lclamped by a bail or clamp element 6. Before being attached together, the stampings at their inner ends are drawn outwardly in opposite directions, relatively to one another, as at 7 and 8, to form between them a non-circular socket for receiving the endl of a mop stick 9. The mop stick 9 is cylindrical in shape, but at the end secured to the cross head has a segmental portion cut awayT to form a flat plane surface 10. `The' drawn portion 8 of one of the stampings has a flat portion corresponding tomthat of the stick so that the socket will conform to .the periphery of the received'end of the mop stick. The socket is of such a size that the endof the mop stick will fit tightly therein, and a staple, taclr, or other suitable securing meansl 11'v may be used for anchoring the cross head to the'end of the mop stick.

A helical coil spring 12 isv provided upon the end ofthe mop stick which fits into the cross head, and loosely surrounds the same so as to freely slide thereon `when free towith either the periphery ofthe sticker the` outer surface of the socket portion 8 of the cross head. In order to turn the spring around the stick it will be necessary to iiex the turn or turns which are flattened over the-flat surface 1() and the flat surface of the socket or cross head, and the force necessary to effect this flexing will resist the rotation of the spring. The forces tending to cause rotation o'f the spring on the stick are small, and this method of securing the spring against rotation has been 'found to be very practical. The spring, at the end adjoining the cross head, may be anchored in any suitable manner to prevent its displacement endwise of the stick, but for convenience the staple 11 which secures the cross head to the end of the mop stick may be passed over one or more turns of the .spring so as to anchor it against displacementl endwise along the stick as well as to secure the cross head to the stick.

A lever 14 has a tongue like extension 15 V`at one end which is bent around a turn of l the coil spring at its tree end, so as to form a hinge connection between the lever 14 and the spring. The ends of the wire or clamping element 6 are pivotally secured to the lever le at a distance from its hinge in the usual manner, and when the lever 14k is operated the spring will serve as a yielding fulcrum and enable the obtaining of a clamping action between the wire 6 and the groove or tunnel inthe end of the head. During the assembly of the mop, with the attached lever 11i,r the spring will be slid over theend of the mop stick before the .cross head is `applied to the stick, and in doingl so the flat portion 10 of the stick will provide a clearance for the hinge extension 15 of the lever. The liat portion 10 of the stick which will lie immediately beneath the hinge extension 15, will enable Athe lever 14l`to move lengthwise of the stick 7 without restriction, and will vnot require `a coil spring 12 of unduly large diameter.

1t willbe observed that with this construction, the non-circular socket and mop ystick will prevent relative rotation between the cross head and stick, and therefore the head can never become loose upon the stick. The staple or other securing means serves to prevent separation of the cross head from the stick and also may anchor the spring lagainst endwise displacement on the mop It will be understood that various changes in the details and arrangements of parts herein described and illustrated for the purpose of explaining the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.

I claim:

l. A mop comprising a cross head having therein a socket of non-circular cross section, a stick having one end corresponding in periphery and size to the socket and fitting tightly therein, whereby the cross head will be mounted upon and held against rotation relatively to the head, a coil spring surrounding the stick adjacent the head, and having a turn conforming closely to the non-circular periphery of the stick whereby rotation of the spring on the stick will be resisted by the resiliency of the said spring turn, means for securing the head against separation from the stick and for anchoring the end of the spring adjacent the head against movement lengthwise of the stick, a lever hinged to the other end of the spring, and a clamping bail arranged in clamping relation to the head and connected to the lever for operation thereby into and out of clamping engagement with the head.

2. A mop comprising a cross head having therein a. socket of non-circular cross section, a stick having one end corresponding in periphery and size to the socket and fitting tightly therein, whereby the cross head will be mounted upon and held against rotation relatively to the head, a coil spring surrounding the stick adjacent the head, the spring at the end adjacent the head closely kconforming to the non-circular periphery of the stick and for the remainder of its length loose on the stick, whereby the tight portion will be resiliently held .against rotation by the non-circular periphery of the stick, means for' securing the head against separation from the stick and for anchoring the end of the spring adjacent the head against movement lengthwise of the stick, a lever hinged to the other end of the spring, and a clamping bail arranged in clamping relation to the head and connected to the lever `for operation thereby into and out of cla-mping engagement with the head.

3. In a mop, a cylindrical mop stick having a segment cut olii for a short distance from one end, a head having a socket conforming in size and shape to and receiving the cut off end of the stick, a cylindrical coil spring surrounding the stick and anchored thereto at the end adjacent the head, a lever of sheet metal having a tongue extension bent around a turn of the spring at its free end which also overlies the flat surface formed by the cut off segment, to form a hinge connection between them, a bail arranged in clamping relation to the head and providing clearance for the hinge extension connected to the lever for operation thereby of the lever lwhen the lever and spring are into and out of clamping engagement With slid over the cut off end during assembly. 10 the head, the cut oli' segment of the stick In Witness whereof, I hereunto subscribe` permitting movement of the lever With the my signature.
